The purpose of this study is to review the current status of disseminating knowledge on Korean people by analyzing biographies for juvenile and general audiences with the subject term 'Korea' in WorldCat. Languages and topics of 15,007 bibliographic records and topic facets, biographees, and holding libraries in the U.S. of 487 biographies for juvenile audiences were analyzed. Major findings are as follows: 1) 30 English biographies are held by may libraries in the U.S. and the most popular subjects are Kim Il-song and Kim Jong-il, 2) 457 Korean biographies are not held by many libraries, and King Sejong and the General Yi Sun-sin are the most popular subjects, 3) many Korean biographies are picture books for the very young readers with the focus on Korean folklores and anecdotal biographies, and 4) there are some errors in topic facets, dispersion of biographees, and inaccurate holding lists of bibliographic records. Therefore, there seems to be little to read with an interest and promote the diffusion of knowledge on Korean people through libraries.

Extensive use of social media applications and mobile devices continues to increase data traffic. Social media applications generate an endless and massive amount of multimedia traffic, specifically video traffic. Many social media platforms such as YouTube, Daily Motion, and Netflix generate endless video traffic. On these platforms, only a few popular videos are requested many times as compared to other videos. These popular videos should be cached in the user vicinity to meet continuous user demands. MEC has emerged as an essential paradigm for handling consistent user demand and caching videos in user proximity. The problem is to understand how user demand pattern varies with time. This paper analyzes three publicly available datasets, MovieLens 20M, MovieLens 100K, and The Movies Dataset, to find the user request pattern over time. We find hourly, daily, monthly, and yearly trends of all the datasets. Our resulted pattern could be used in other research while generating and analyzing the user request pattern in MEC-based video caching scenarios.

Along with the popular use of commercial drones, there are increased concerns on the possible threats from drones intruding into secured areas. The difficulty of drone detection is attributed to its stealthy operation flying at low altitude with low level signature. Consequently, the anti-drone technique has been of major research topic in recent years and among others, the radar detection is considered as the most promising technique. However, the use of conventional radar detection may not be effective due to the low level radar cross sections of the commercial drones. In this paper, ISAR technique has been employed to implement drone detection in urban area. To this purpose, a pulsed radar system is set up on the ground to track flying drones and the corresponding ISAR images are produced by coherent processing.

Music was made popular through the modern mass media. Nonetheless, if a period of high standard performances and appreciation by a minority of culture connoisseurs can be qualified with the expression "gentrification of culture", then a period when anyone can access culture through the mass media can be qualified with the terms "popularization of culture" and in this period the reorganization of performance culture can only be driven by the public. In fact, the Jabga, which is a type of traditional song that received strong public adhesion by means of phonograph records and radio broadcasts at the time, stands as a typical example to it. Gagok and Sijo up until the 1920s and even the 1930s are believed to engage actively in the changing media environment and the new modes of music enjoyment and transmission. The Album recording of faster rhythm music and the inclusion of the Sijo, Jabga, and folk songs in one broadcast programme can be seen as reflecting such an effort. However, it can only be hard for the Sijo and Gagok to challenge the predominance of the Jabga which made its lyrics more popular and the new songs written in accordance with the new media environment. Until the 1930s in this changing environment of music enjoyment, Gagok and Sijo performers rather sought to distinguish themselves from the existing popular song style by reproducing traditional forms. The album recording and broadcasting of Lee Wangjik Aakbu, the beginnings of local singers, the participation of male performers not only contributed to the diversification the enjoyment culture of songs and sijo, but also made the 'difference in standard' with the popular songs even more salient.

There is a common misbelief that female gamers prefers simple cute easy games so that they are incompetent if higher skill level is required or disqualified to be a winning party member in MMORPG. This pink game theories are the results of video game analysis done in US and Europe way before online games and mobile games become popular thus. there are many evidences that such misconceptions do not hold anymore. However, researches on gender game culture and gender preferences have not been seriously conducted since 2007 in Korea. Thus, in this paper, we surveyed 88 male and 151 female gamers from their late teens to 30s and found a gap between behavior and perception due to serious gender stereotypes. Gender differences are still found in several areas, but the degree of differences were weakened or in different direction from 2007. The game design to attract female gamers should understand such gender gaming culture and gender difference.

This study investigated the effects of song discussion on depression and rehabilitation motivation in stroke patients. Older adults with chronic stroke participated in this study: nine for the experimental group and eight for the control group. The experimental group was divided into three subgroups and participated in 12 sessions over 6 weeks. Target lyrics were selected by the investigator among popular songs from the participants' young adulthood. The song-based discussion was facilitated to address issues targeted at supportive, insight-focused, or reconstructive stage. The control group was provided with delayed intervention. At pre and posttest, the short form of Geriatric Depression Scale and the Rehabilitation Motivation Scale were measured. The experimental group showed significantly decreased depression and significantly increased rehabilitation motivation (p < .01), while the control group showed no significant changes. Positive changes were also observed in all subcategories of rehabilitation motivation in the experimental group, particularly in significantly increased task-oriented motivation and decreased amotivation. This study suggests that song discussion will be effectively applied in rehabilitative settings to address psychological issues of older adults with stroke.

This study aims to decode newly 'Mojookjirangga' of the Sillian songs on higher viewpoint that is to integrate previous decodings; furthermore to discuss a musical composition of the Sillian song. So to speak, when we read 'hoe(廻)' as 'gam(감)-' instead of 'dol(돌)-' in the song 'Mojookjirangga' which was written in Chinese Characters, such a decoding contributes largely to grip the deep meaning-structure of the elegiac song. Consequently we are able to sing that 'Mojookjirangga' according to the characteristics of national music. However the characteristics of national music are 1) the length of a phrase makes a rhythm, 2) the first beat is strong beat and becomes more and more weak, 3) there are shaking sounds on the long rhythm and changing vowels, 4) there is deep and great dignity in those national music songs. Then we can find those characteristics easily at Sijo-songs. In fact, the Sillian songs and Sijo-songs of Chosun period are more popular music. Then we are going to sing 'Mojookjirangga', referring to the method of Sijo-song and the characteristics of national music. Nowadays such an attempt is to contribute to enrich our national culture and to make the global Korean-stream more abundant.
